Abstract | OBJECTIVES: METHODS: Data from two trials assessing the efficacy of abatacept in MTX inadequate responders were pooled for this exploratory post hoc analysis. Patients with disease duration of ≤ 2 years at baseline (early disease), originally assigned to an abatacept approximately 10 mg/kg treatment arm and entered into a long-term extension (LTE), were compared with patients with ≥ 10 years of disease (long-standing RA). Remission, DAS28-CRP, ACR 70 responses and the Routine Assessment of Patient Index Data 3 (RAPID3), improvement in physical function as measured by the Health Assessment Questionnaire Disability Index ( HAQ-DI). RESULTS: Twenty-three percent of these patients (n=108) had early disease. A higher percentage of patients with early disease achieved DAS28-CRP remission versus patients with long-standing disease (35.2% vs. 19.4% at year 1, p<0.01; 46.0% vs. 30.9% at year 3, p<0.05). In addition, a higher percentage of the subgroup with early RA achieved ACR70 responses. More patients with early RA had a meaningful improvement in their HAQ-DI (75.2% vs. 60.4%; p<0.05) and RAPID3 scores at one year (mean changes from baseline of -9.6 vs. -8.1; p=0.009). CONCLUSIONS: These data provide additional support for the possible use of abatacept in biologic-naive patients who have had inadequate response to MTX, earlier in their disease course.
